I would just say this. What is your check raise % according to PT. Probably not higher than 5% on the flop (if even that high). Now, in a full ring game you're playing about 17% of the hands. In EP less but the blinds more so it will even out to the first 5 positions (those you're most likely to checkraise) to about 17%. That means in 100 hands you'll be in 17. Of those you'll check/raise maybe once. Now the guy that you check/raised may remember it happening but most of the rest of the table won't. Most online players don't play much more than 100 or 200 hands at any one table. You can see what I'm getting at here. I just don't buy that you're typical low limit player is going to pay that close attention to the fact that you check/raise once in 100 hands. Hell, if he knew that fact he may even think that you don't hardly ever check/raise and be more likely to bet than fear you.
